lineax v0.1.0

Phew, it's been a while since a release! It's about time we got something out.

Breaking changes

• AbstractLinearSolver.allow_dependent_{rows, columns} have been removed in favour of the simpler AbstractLinearSolver.assume_full_rank. (Thanks @adconner! In particular for being so patient with me and my bugs 😅 #158)

Features

• Added the lineax.LSMR solver. This is a solver that will return the pseudoinverse (like lineax.SVD) solution, and handles nonsquare/singular matrices. In addition, it is an iterative solver. (Thanks @f0uriest @PTNobel @healeyq3 @johannahaffner! #86)
• Added the lineax.Normal solver. This wraps another existing solver so that it operates via the normal equations. (Thanks @adconner! #159)

Compatibility

• Now compatible with modern JAX (at least 0.8.2), which was newly promoting some static values to tracers. (#183, #187, #188)

Bugfixes

• Preconditioned Krylov solvers now also use the preconditioner on the backward pass, instead of no preconditioner. (Thanks @f0uriest! #162)

Performance

• Improved performance of tridiagonal solves. (Thanks @jpbrodrick89! #152)

New Contributors

• @f0uriest made their first contribution in #162
